ARMSTRONG, residing at '-Thisinve'ntion relates to improvements in4 line-- casting machines of the linotype class and more particularly to the matrix handling-.and transferring mechanism. l v

The 'rimary object of the inventionis tot provide an automatic stop against which the lineof matrices abut when they enter the first elevator nd while the line of matrices is being carried by such elevator to the casting position, such .stop serving to prevent turning or other displacement of the matrices and accommodating itself automatically to lines of different lengths, thereby enabling the machine to be, adjusted. for lines of different lengths without requiring manual adjustment o the stop by tlie operator.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as fully described, the novel features being pointed out particularly 'inftheclaims at the end of the specification.

' Inthe accompanyin drawin szfFigures l,V 2 and 3 show one orm of t e invention applied to the first elevator of a line cast- 1 showing the device in front elevation with parts in section, Fig. 2 'being a-pers'pective of the upper portion of the firstzelevatorwith the sto-p applied thereto; vand Fig. 3 is a perspective view of the line stopv removed from the elevator; Figs. 4 and 5 show another embodiment of the invention; Fig. L representing l a transverse section through the jaws of the first elevatorg and Fig. 5 a perspective of the stop and e. Similar parts are designated by the same reference characters in the several views.

The invention in the present instance is shown'applied to a line casting machine o linotype class-wherein each line of matrices is composed by manipulation of the keyboard and delivery mechanism operates to convey the line of matrices longitudinally into what is commonly known tents 10 at one end elusive, a stop as the irst elevator. This elevator embodies a slide l havingan overhanging head. to which a jaw 2 is iXed, a coperating jaw 3 being arranged opposite to the jaw 2 and is fixed to and spaced therefrom by an interposed blook 4f. These .opposed jaws vprovide a channel or passageway for the matrices M, and in the construction shown, the elevator is capable of receiving matrices when assembled at two different levels whereby either of two characters on each matrix may be used. The opposed faces of the jaws which constitute the walls of the passageway are in the present instance channeled at 5 and 6 to receive the lugs at the upper corners o the matrices, these channels. forming ledges 7 and 8 which coperate with the lugs ofthe matrices assembled at the lower level, thereby supporting these matrices. A rail 9 is fitted into the lower portion of the jaw 2 and serves to support the matrices assembled at the upper level, this rail being capable of retraction to permit the matrices at the upper level to drop to the lower level prepara tory to the transfer of the line of matrices from this elevator to the matrix-distributing mechanism. In the operation of machines of this class, thefdelivery mechanism conveys the line of matrices into the first elevator while the line is confined in an endwise direction, whereupon the elevator lowers the line of matrices to the casting position. While the elevator is carrying the line ofy matrices from the delivery mechanism to the casting position, the delivery mechanism cannot operate to prevent turning or other displacement of matrices in the line. Experience has shown it to be desirable to provide stops on the first elevator to coperate with both ends of the line of matrices displacement of the matrices, due to jar of the machine or other causes. It is customary to employ either one or a pair of spring-operated defor the purpose of preventing prevent the end matrices in the line from falling back after the line has been delivered to the elevator. The present invention prothe opposite' end of the line of matrices whereby the line of matrices is coniined in` such manner as `to prevent displacement thereof. Inthe construction shown in Figs. 1-3 in- 11 is used, this stop embodyof the irstelevator to vvides an automatically adjustable stop for f ing a pair of side members 12 and 13 which are adapted to lit and slide longitudinally in the channels 5 and 6 of the elevatonjaws. Preferably, the friction between the side members of the stop and the jaws of the elevator is utilized to retain the stop in operative position. The side members of the stop are preferably connected at one end while they are unconnected at the opposite end of the elevator, forming an open passageway between them, as shown. The line of matrices when introduced into the second elevator abuts against the ends of the side members 12 and 13 at the open ends thereof, the stop being pushed to the left in Fig. 1 as the line of matrices enters the elevator. According to the present invention,

' this stop is automatically reset after each operation by the slide which transfers the line of matrices to the distributing mechanism after the cast has been made. This slide 14 may be of the usual construction, it being shown as mounted to operate in the guide 15 and provided. with the usual link 16 for reciprocating it at appropriate intervals. The stop for the line of matrices is provided with a" longitudinal bar 17 which may be formed as a part thereof, and said bar is slidable in a slot 18 formed in the top of the elevator jaw 3 and is provided with an operating projection 19 which is exposed above said jaw. The line transfer slide 14:

is provided with the usual member 20 which serves to push the vline of matrices out of the elevator and into the distributing mechanism, and said slide is also provided with an arm 21 which is fixed thereto and provided with a hook 22 which, when the line transfer slide moves to the right in Fig. 1 to remove a line of matrices from the elevator, coperates with the projection 19 of the line stop and carries said stop toward the right in readiness to be engaged and pushed toward the left by the next incoming line of matrices, the stop being retained in the position to which it is advanced by the line of matrices by reason of the frictional engagement between the stop and the elevator. In order that the elevator may descend while the line transfer slide is at the receiving end of the elevator, the arm 21 preferably extends upwardlyfrom the slide in rear of the elevator jaw 3, thence extending forwardly, and thence downwardly througlf the space between the elevator jaws.

The construction shown in Figs. 4 and 5 enables a relatively shorter line stop to be used as compared with that shown in Figs. 1-3 inclusive. In this instance, the line stop 23 embodies side members 24 and 25 which operate frictionally in the channels 5 and 6 of the elevator jaws, and the line delivery slide 27 carries an arm 28 which is pivoted on a pin 29 supported by the slide, and a spring 30 operates to yieldingly hold the arm in a horizontal position and in line with the stop 23. In this construction, the stop is moved toward the right hand matrixreceiving end ofthe elevator by the arm 28 when the line delivery slide 27 moves in said direction to transfer the line of matrices from the elevator to the distributing mechanism after a cast has been made from that line and the next incoming line of matrices engages and pushes the stop toward the left, the stop remaining in the position to which it has been advanced by the matrices owing to the frictional engagement between the stop and the elevator, thus preventing turning or other displacement of the matrices. The elevator may descend to convey the line of matrices to the casting position before the line delivery slide returns to its initial left-hand position, the arm 28 being deflected downwardly by the elevator jaw 3, as shown in Fig. 4, and thus permitting descent of the elevator without interference.

In both forms of the invention,` each line of matrices is held or confined at both ends while the elevator is conveying the same to the casting position, dropping back of the matrices at the rear end of the line being prevented by the detent or detents 10 while turning or other displacement of the matrices at the forward end of the line is prevented by the movable stop. This stop is particularly useful in connection with machines of the linotype class which embody means for adapting the same for the composition and casting of lines of different lengths, as the stop accommodates itself automatically to the length of the line andhence requires no setting or manual adjustment by the operator when the length of the yline is changed, and the stop is automatically moved toward the receiving end of the elevator preparatory to the reception of each line of matrices and will be advanced by the incoming line of matrices a distance determined by the length thereof.

I claim as my invention 1. In a machine of the linotype class, the

combination of the first elevator, a line stop reciprocable in the matrix channel of the elevator adapted to be advanced by an incoming line of matrices, and means for moving the stop toward the receiving end of the elevator preparatory to the receptionof a line of matrices.

2. In a machine of the linotype class, the

combination with the first elevator, of a line stop frictionally engaging the elevator and adapted to be engaged and advanced by an incoming line of matrices, and means for moving the stop in the matrix channel and toward the receiving end of the elevator when a line of matrices is removed from the elevator.

3. In a machine of the linotype class, the

combination with the first elevator and the said elevator line transfer slide, of a line stop reciprocable in said elevator, and means for engaging the transfer slide with the line stop to move the latter to the receiving end of the elevator.

4. In a machine of the linotype class, inl combination with the first elevator, a line stop reciprocable in the matrix channel of having a normal position at the receiving end of the elevator and adapted to be moved out by the incoming matrices, and automatic meansl for returning said line stop to its normal position.

5. In a machine of the linotype class, the combination with the vertically movable first elevator and the cooperative line delivery slide, of a line stop movably carried by the Copies of this patent may be obtained for elevator and adapted to be advanced to different positions by an incoming line of matrices, and means for connecting said stop to the line delivery slide when the elevator is in elevated nosition whereby the operative movement of said slide will automatically move the line stop toward the receiving end of the elevator.

In testimony whereof I lhave hereunto set my hand in presence of two subscribing witnesses.
